For low wear applications against soft metals in "non-lube" conditions such as:

  • Cylinders
  • Disks
  • Rings
  • Washers
  • Bearings

Benefits

  • Lowest wear rate in dry service
  • Excellent wear against soft metals like aluminum, brass, bronze
  • Excellent coefficient of friction
  • Good creep resistance
